An article by EWI applications engineer Adam Uziel, “Looking at Large-Scale, Arc-Based Additive Manufacturing,” has been published in the April 2016 issue of Welding Journal.

In the article, Uziel explores EWI’s recent work in using pulsed gas metal arc welding for producing large-scale, stainless-steel parts using a layer-by-layer approach. EWI’s demonstration build resulted in an 85% reduction in material when compared to machining the same part from a solid forging or casting. Additionally, utilizing the arc-based additive process required 15 h of arc time compared to the traditional method of forging or casting of 40-50 h. Uziel states that many industries could benefit from arc-based AM, including aerospace, oil and gas, nuclear, shipbuilding, and heavy fabrication. He points out that additional software development is required to accommodate the specific needs of arc welding processes. Read the full article in the April issue of Welding Journal.
